Frequently Asked Questions – we have answers

Both models are based on the same inflatable Dropstitch platform and are transported inside the car. The Classic (12.5 kg) is the purist base with everything essential. The Comfort (approx. 14.5 kg) additionally offers:

• SkyView roof – open view of the starry sky
• Blackout coating – sleep in darkness and cool comfort
• Rain-protected entrances
• Additional pockets in the inner roof

Setup works in three steps:

• Inflate the Dropstitch platform using the included piston pump (like a SUP board)
• Assemble the tent on the inflated platform using the aluminium poles
• Place the finished tent on the car's roof rack and secure it with the straps

One person can do all of this alone, without tools, in just a few minutes.

The sleeping area is 220 × 130 cm – enough for two people. The interior headroom is approx. 120 cm. When set up on the car, the tent barely exceeds the normal vehicle height.

The packed dimensions are 75 × 48 × 40 cm – barely larger than a travel bag. It fits in home wardrobes, storage rooms or the boot of your car. No garage or carport needed.

Yes. With the optional WEEKEND Stage (aluminium platform, approx. 50 cm height, under 9 kg) the tent can be set up on any surface – without a vehicle, without climbing. The Dropstitch platform can also be used separately as an airtrack, guest bed or play mat for children.

Since the WEEKEND is transported in the boot during driving, a roof load of just approx. 10 kg is sufficient – enough for the roof rack. This makes it suitable for almost all vehicles: small cars, electric cars, used cars. It can also be used on rental cars and car-sharing vehicles, as long as a roof rack can be mounted.

Not necessarily – the Dropstitch platform is already a stable, level sleeping surface. For optimal sleeping comfort we recommend the Wechsel Vasta 5 sleeping mat, which fits the sleeping area perfectly.

No – a piston pump is included in the delivery. You can additionally use an electric pump or compressor, which speeds up setup further. An electric pump is recommended for older campers or if you set up the tent particularly frequently.

• Inflatable Dropstitch platform (TPU fabric)
• Tent made of ripstop polyester (UV 50+, 5,000 mm water column)
• Aluminium poles (16 mm) for tent assembly
• Piston pump with long hose
• Extendable aluminium ladder (up to 2.30 m)
• Repair kit (adhesive patches)
• Stuff sack bag
• Assembly instructions

Yes. The ripstop fabric has a water column of 5,000 mm and reliably protects against rain. The WEEKEND Comfort additionally offers rain-protected entrances. Thanks to its elevated position on the roof, you stay dry even in heavy rain – far from the ground and rising moisture.

• Elevated position: Independent of ground conditions, mud, sand, crawling insects
• Comfort: Firm, level sleeping surface – no inflating, no air loss like with sleeping mats
• Flexibility: Sleep wherever you're allowed to park
• Safety: Elevated access gives a greater sense of security, especially when travelling alone
• View: At best, the starry sky directly above your bed

With a permanently mounted roof tent, most manufacturers recommend a maximum speed of 120 km/h. Since the WEEKEND is transported in the boot during driving, there is no speed restriction during transport. Please check the relevant legal regulations before travelling abroad.

Basically on any vehicle with a suitable roof rack – with the exception of convertibles. The important thing is that the dynamic roof load is sufficient. You can find this in your vehicle's owner's manual. If in doubt, contact us with the make, model, year of manufacture, roof load and information on whether a roof rail is present.

The dynamic roof load is stated in your vehicle's owner's manual – not in the vehicle registration document. Note the distinction: the dynamic roof load applies while driving (the relevant figure for roof tents). The static roof load applies to a stationary vehicle and is much higher. If unclear, the manufacturer or a garage can help. Note: A panoramic roof often reduces the roof load by 20–25 kg.

Yes – children love roof tents! The elevated sleeping feels like a treehouse. Please note: young children should be accompanied when climbing the ladder. With the WEEKEND Stage, the ladder is eliminated entirely – entry is then at a comfortable knee height.

Our roof tents do not have an integrated power connection. We recommend a power bank or portable battery for charging devices. Exception: The premium models Alvar and Tjelvar feature integrated LED lighting with a USB connection.

Yes – selected spare parts are available in our shop. Should something break on a trip, our service team is on hand with advice and spare parts available for short-notice delivery. Simply contact us at info@groenberg.com.

• Anti-theft nuts: Special screws that can only be removed with special tools
• Padlock: Ring-head nut with padlock on the mounting screws
• GPS tracker: Hidden tracker in the tent as additional security
• The WEEKEND has a particular advantage: it is transported inside the car and is therefore not at risk of theft while driving.

Softshell (fold-out tent):

• Significantly lighter than hardshell
• Sleeping area doubles when unfolded
• Usually has a covered entrance
• More affordable in price
• Setup takes slightly longer, more susceptible to wind

Hardshell:

• Very fast setup (often under 1 minute)
• More aerodynamic, quieter while driving
• Storage space for duvet, pillow, sleeping bag
• More legal pitching options (tent does not extend beyond the vehicle)
• Higher weight, higher price

We recommend softshell if you: want a larger sleeping area, have a smaller budget, or don't want to permanently mount the tent on the roof. We recommend hardshell if you: want maximum speed when setting up, drive a lot and value aerodynamics, or want to leave the tent permanently on the vehicle.

Inflatable (unique category): WEEKEND Classic, WEEKEND Comfort

Softshell: Halvor, Alvar

Hardshell: Tjelvar, Villmark

This depends on the model – ranging from non-removable to fully removable. You can find the exact details in the respective product description. This can also be seen from the product photos.

The standard telescopic ladders are 2.3 m long. For particularly tall vehicles (SUVs, vans), an additional 2.6 m ladder is available. The WEEKEND uses the same standard ladder and is therefore perfectly suited to most common car heights.

The dynamic roof load indicates how much weight may be transported on the car roof while driving. It is stated in your vehicle's owner's manual. The total weight of the roof rack (~5–8 kg), tent and any additional luggage must not exceed this value. It differs from the static roof load (applies only to a stationary vehicle and is much higher).

• WEEKEND Classic / Comfort: min. 10 kg (transported in car, only rack needed)
• Halvor (68 kg): min. 75 kg roof load
• Alvar (77 kg): min. 90 kg roof load
• Tjelvar (81 kg): min. 100 kg roof load

Rule of thumb: tent weight + rack (~7 kg) must not exceed the dynamic roof load.

Yes – the WEEKEND Classic and Comfort are suitable for almost all vehicles since they are transported inside the car. Even small cars (VW Polo, Renault Clio, Opel Corsa) with 75 kg roof load are suitable for the Halvor. Electric cars such as the VW ID.3 or Dacia Spring do not permit roof luggage according to the manufacturer – here only the WEEKEND is suitable, provided a rack can be mounted. The VW ID.4 (75 kg) can also be used with a Halvor.

Yes, significantly – often by 20–25 kg compared to a standard roof. Some manufacturers do not permit any roof racks with a panoramic roof. Always check the model-specific owner's manual for the relevant trim level.

The WEEKEND is particularly well-suited for this, as it is very light and mounting is quick and tool-free. Please check with the rental provider in advance whether roof racks and roof tents are permitted. Most rental cars have no roof racks – you would need to acquire a suitable rack separately and fit it accordingly.

For the WEEKEND no tools are required – installation is completely tool-free. For all other Groenberg models, all necessary tools for attaching to the roof rack are included in the delivery. A ratchet wrench is not strictly necessary but makes installation considerably easier.

The WEEKEND (12.5 kg) is specifically designed for solo installation. One person can carry it alone, set it up on the roof and remove it again – without any help, without tools. For heavier models such as the Halvor, Alvar or Tjelvar we recommend at least two people or a mounting stand.

The WEEKEND is equipped with a strap system that fits almost all common roof rack systems (steel and aluminium profiles). Compatible with Thule, Yakima, Kamei and other standard systems. The rack spacing should be between 60 and 120 cm.

The standard ladder is 2.3 m long. It is well-suited for vehicles up to approx. 1.6–1.8 m roof height (including roof rack). For taller vehicles such as SUVs or vans we recommend the optional 2.6 m ladder.

Yes – provided you have suitable crossbars that clip into the roof rails. These are available separately and are adapted to the vehicle length. Roof rails alone without crossbars are not sufficient.

No – all Groenberg roof tents are factory waterproofed and can be used without any pre-treatment. Should the waterproofing diminish after a few years, we recommend a specialist waterproofing spray for outdoor fabrics – please test on an inconspicuous area first.

• Carefully brush off dried dirt with a soft brush
• Remove the mattress cover and machine wash at 30° on a gentle cycle
• Vacuum the tent interior with a handheld vacuum cleaner
• Clean the tent fabric with mild detergent and a soft sponge
• Allow to dry completely before packing away

Light mould can be treated with a water-vinegar mixture (1:1). For stubborn mould we recommend a specialist mould remover for tent fabric. Important: allow the tent to dry completely afterwards and store it open.

Briefly yes – in a sudden departure you can pack the tent away wet. However: it must be set up to dry at the latest after 2–3 days. Storing it continuously wet or damp promotes mould growth and damages the fabric.

The roof tent should be stored dry and not completely sealed – slightly open or with ventilation to prevent mould formation. It must not be under any load during storage. Thanks to its packed dimensions, the WEEKEND fits in any cellar or wardrobe.

The TPU Dropstitch platform is very robust and easy to care for. After use:

• Rinse with clean water (especially after beach or salt spray use)
• Allow to dry completely before rolling up
• Use the small repair kit (included in delivery) for punctures or scratches
• Do not bring into contact with sharp objects

The WEEKEND Stage is an extendable aluminium platform (192 × 130 cm, approx. 50 cm height, under 9 kg, packed dimensions 76 × 25 × 20 cm). It enables the WEEKEND to be set up without a vehicle – on campsites, in the garden or at festivals. Particularly popular with older campers and people with physical limitations, as entry is at a comfortable seated height – no ladder required.

The WEEKEND Bridge is a rollable mat with integrated aluminium supports, similar to a slatted frame. It bridges the gap between the roof bars and prevents the Dropstitch platform from sagging under higher loads. Recommended for vehicles with a large spacing between roof bars.

The WEEKEND Speedbag is a waterproof transport bag that allows the packed WEEKEND to be transported on the roof rack – keeping the boot free. With a large roll-closure opening and straps for secure fixing on the roof.
